Jenkins ver. 2.89.2
Pipeline: Declarative 1.2.6
Up until very recently the Jenkinsfile example below with reusable docker agent definition worked great, however after rebuilding Jenkins using latest LTS docker image and reinstalling latest plugins from scratch I'm now getting ClassCastException as it seems to confuse docker 'label' and docker { options } formats.
java.lang.ClassCastException: org.jenkinsci.plugins.pipeline.modeldefinition.agent.impl.DockerPipeline.image expects class java.lang.String but received class org.jenkinsci.plugins.workflow.cps.CpsClosure2
Caused: java.lang.IllegalArgumentException: Could not instantiate {image=org.jenkinsci.plugins.workflow.cps.CpsClosure2@614e9b7d} for DockerPipeline(image: String, alwaysPull?: boolean, args?: String, customWorkspace?: String, label?: String, registryCredentialsId?: String, registryUrl?: String, reuseNode?: boolean)
def node = {
label 'bar'
registryUrl 'example.com'
image 'node:1.2.3'
args '--shm-size 1g'
}
pipeline {
agent none
stages {
stage('0') {
agent { label 'foo' }
steps {}
}
stage('1') {
agent { docker node }
steps {}
}
stage('2') {
agent { docker node }
steps {}
}
stage('3') {
agent { docker node }
steps {}
}
}
}
